Habahe Gr
Type Locality and Naming
It was not designated type section by the author. Xinjiang Bureau of Geology and Mineral Resources (1999) selected the Section of Daqinggeli River at Qinghe County, Northern Xinjiang (90°22′20″E, 46°41′40″N) as the reference section. The Habahe Group was derived from the Haba Series proposed by No.13 Party of Geology, Ministry of Geology and Mineral Resources (1955-1956), and was published by Xiao Bing (1979).
Synonym: (哈巴河群); In 1943, Li Chengsan named a very thick sequence of green schist the Songkemu Series when he made a gold deposit survey in Altay Mountain. The No.13 Team of Geology, Ministry of Geology and Mineral Resources (1955-1956) suggested that Li's Songkemu Series is equivalent to the Haba Series yielding Middle-Late Ordovician coral and bryozoan of Kazakhstania, and redefined it the Haba Series which was renamed the Haba Gr by Xinjiang Party of Regional Geological Survey when they compiled the geological map of Altay area in 1965-1966. Their consideration was followed by Xiao Bing (1979, 1990).
Lithology and Thickness
The Habahe Group is characterized by a sequence of gray, grayish green metamorphosed clastic rock. Thickness of the group records incomplete 6000 m. [For graphic purposes, "clayey sandstone" used here for the generalized "clastics"]
